HASP-IOCK.

Specification of Letters Patent.

Patented Apr. 26, 1910.

Application filed January 20, 1910. Serial No. 539,098.

To all whom it may concern.'

Be it known that I, ALAN L. JERVEY, a citizen of the United States,residing at Richmond, in the county of Henrico and State of Virginia,have invented a new and useful Hasp-Lock, of which the following is aspecification.

This invention relates to hasp locks and is more particularly designedas an improvement upon the structure disclosed in Patent No. 906,803,issued to me December' 15, 1908.

One of the objects of the invention is to simplify and otherwise improveupon the patented structure and to provide means whereby the hasp can beemployed for holding a door or gate in closed position without theynecessity of shooting the bolt into engagement with the keeper'.

A still further object is to provide means whereby the base of thekeeper becomes seated within the hasp base so as to permit the hasp tolie close to the supporting structures while it is in engagement withthe keeper.

Another object is to provide an improved guard constituting means forpreventing the rotation of any key other than the proper one, within thelock.

A still further object is to provide a key receiving plug or barrelrequiring the use of a special form of key.

With these and other objects in view the invention consists of certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claims.

In the accompanying drawings the pre ferred form of the invention hasbeen shown.

In said drawings, Figure 1 is a view partly in elevation and partly insection of a hasp lock embodying the present improvements, the haspbeing shown raised above the keeper. Fig. 2 is a central longitudinalsection through the hasp lock and showing the same in engagement withthe keeper. Fig. 3 is a perspective view of the guard plate. Fig. 4: isan elevation of the key receiving plug. Fig. 5 is an elevation of a keydesigned to be used in connection with the lock.

Referring to the figures by characters of reference 1 designates thebase of the hasp lock, the same having an elongated loop 2 formedintegral therewith and which is movably mounted within a staple 3secured to a door, gate, or other supporting strueture. The base llias acircular recess 4 designed, when the lock is in use, to receive thecircular base plate 5 of the keeper 6, said keeper being in the form ofan arched or staple like member' secured in any preferred manner to thebase plate 5 and having apertures for the reception of suitable securingmeans such as shown at 7.

The casing 8 of the lock has a desired number of studs 9 extending fromthe open face thereof and which are designed to be seated in openings inthe base 1 and to be upset or riveted therein so as to hold the casingfixedly upon the base 1. A -slot 10 is formed within the base adjacentthat end thereof farthest removed from loop 2, this slot being soproportioned as to readily receive the keeper 6. Reinforcing ribs 11 areformed on the base adjacent the ends of the slot and a stop lug 12 ispreferably formed within the casing 8 adjacent the slot and for thepurpose hereinafter set forth. A recess 13 is formed in the inner' faceof the top of the casing 8 and directly opposite the slot, this recessbeing designed to receive the crown portion of the keeper when it isinserted into the casing.

Base 1 is provided between the slot 10 and one end portion of the casing8 with a raised portion 14 constituting a wear device on which ismounted a sliding bolt 15. This bolt travels between guide ribs 16upstanding from the base and one end thereof is beveled as shown at 17,thc advance portion of said end being movable into an inserted keeper'and against the stop 12. A stud 18 is formed at the other end of thebolt and is surrounded by a coil spring 19 which bears against theadjoining wall of the casing and thus serves to hold the bolt normallypressed against the stop 12 and with its beveled portion extendingacross the slot 10.

A recess 20 is formed in one side of the bolt 15 and the side of thisrecess is normally closed by fingers 21 extending from one end of aguard plate 22. This plate is formed integral with and extends upwardlyfrom a base 23 which is riveted 0r otherwise fastened to the base 1 andhas a circular opening 2i within which is journaled one of the reducedends 25 of a revoluble plug or barrel 26. The other end of this plug isjournaled within the top of the casing 8. Diametrically opposedlongitudinally extending slots 27 are formed within the plug 26, theybeing spaced apart by a bridge or partition 28.

The key 29 to be used in connection with the lock has a longitudinalslot 30 in its shank and is so proportioned as -to receive this bridge,the ward 31 of the key being slotted so as to pass between the fingers21 when the key is rotated. As shown in Fig. 1 the guard plate 22constitutes an additional guide for the bolt, there being an upstandingguide rib 32upon the baseand directly opposite this plate, said rib alsoforming a guide for the bolt. y

The free end of the base 1f has a stud 33 extending therefrom andprovided with recesses 311 in its side edges. This stud is designed tobe inserted into the keeper 6 when the hasp is merely utilized for thepurpose of holding a gate or door in `closed position without lockingit. When it is desired to lock the gate or door, however, the hasp isplaced over the keeper and forced thereonto so as to cause the saidkeeper to press against the beveled face of the bolt and shift said boltout of the path of the keeper. As soon as the crown portion of thekeeper becomes seated within the depression 13, the tensioned spring 19shifts the V,bolt into the keeper and thus locks the hasp thereto.

When it is desired ,to unlock the hasp the proper key is inserted intothe plug 26 land rotated. rlhe ward will pass the guard plate'QQ andmove into the recess `20,;the edge of the ward following the pathindicated by the dotted line i-n Fig, l. The 4bolt will therefore beretracted and the vrhasp can then be withdrawn from the keeper.

It will be noted that when the keeper is seated within the lock, theintermediate portion thereof rests within the depression 13 while thebase portion of the keeper is engaged by the base l. It will beapparent, therefore, that, inasmuch as the keeper is firmly held at itsouter'and inner portions, it will be prevented from bending out of iproper position should -it 'be subjected to departing from .the spiritor sacrificing lateral strain and it is always held in position toproperly receive the bolt 15.

It is of course to be understood that various changes may be made in theconstruction and arrangement of the parts without an of the advantagesof the invention as del-7 iined in the appended claims.V

What is claimed is 1. In a` device of the class described including akeeper, a loosely supported hasp mounted for sliding and swingingmovement, a keeper receiving casing upon the hasp, and means outsideofthe casing and fiXed relative thereto for engaging the keeper.

l2. A device of the class described includi Y ing a keeper having abase, a hasp mounted for sliding and swinging movement and having arecess for the reception of said base and a slot for the reception ofthe keeper,

and means within the casing for engagingV the keeper, said basecooperating with the Vwalls of the recess 'to hold the hasp and y withinthe base of the hasp for the reception of the keeper and a depressionwithin'the casing structure constituting a seat for the intermediateportion of the keeper, anda spring controlled locking bolt movably.

mounted in the keeper.

4L. A device of the class described incl-uding a keeper, a hasp mountedfor sliding and swinging movement `and including a casing, there being aslot in the bottom of the casing for the reception of the keeper, aspring controlled bolt slidably mounted within the casing and movableinto the inserted keeper, a guard plate within the .casing andconstituting a guide for the bolt, said bolt having a key ward receivingrecess normally closed by the plate.

5. A keeper, a hasp, means lfixed .relative to the hasp for insertioninto the keeper, and separate means carried by the hasp for receivingand engaging the keeper.

6. A device of the class described including a casing having a keyreceiving opening, a recessed bolt slidably mounted within the casing'aplate secured to the casing and having an upstanding fingered guard,lsaid guard constituting a guide -for the bolt `and normally closing therecess, the fingers on the said guard being so disposed as to preventthe movement of any but a predetermined key into the recess to shift thebolt.

7. The combination with a casing and a bolt slidably mounted therein andhaving a recess for the reception of the ward of a key, of a bolt guidenormally extending across the recess in the bolt and constituting aguard to prevent the movement of any but a predetermined key into therecess to shift the bolt.
